For-profit college fever is spreading in the U.S. Senate. Yet another committee (the third, by our count) plans to hold a hearing examining possible malfeasance by higher education companies, with Senator Tom Carper (D-Del.) announcing a March 2 hearing of the Subcommittee on Federal Financial Management, Government Information, Federal Services and International Security, which he chairs. Carper said the hearing would examine the flow of money from the Defense Department's Tuition Assistance Program to current service members enrolled at for-profit colleges, and allegations in recent news reports that, as he put it, "some bad actors have taken advantage of our military personnel and have failed to deliver the quality of education they promise to our men and women in uniform." Unlike most of the Senate hearings about for-profit colleges in the last 18 months, this one will not occur in the hotbed of career college scrutiny: Senator Tom Harkin's Committee on Health, Education, Labor and Pensions. But Harkin will still play a role: the Iowa Democrat is scheduled to be a star witness.
